Ro,
You asked about drysuits in general. I have two CF-200's from DUI. One is the CF-200X custom cut for me with many modifications done by the factory. The other is one that I bought used, and had the factory rework for me. The used suit had been used by an oyster diver, and it stood up to that hard usage quite well.
They are somewhat more expensive, but if cared for properly, you should get at least 10 years diving, and usually more, from them.
The crushed neoprene used by DUI is tough, and comfortable, and does not compress with depth. It is pre-compressed. It also offers some insulation, so in moderate waters, thick undersuits are not necessary. If you get the front entry suit, getting it on and off is a breeze.
If you get a new suit, get the factory's Zip-Seals on at least the wrists, and get a spare set. If you tear a seal, replacing it standing on the deck of the dive boat is child's play.
Last but not least, get the Rock Boot option. I have to transit rocky shores carrying equipment, and move around on the deck of boats littered with heavy equipment. The Rock Boots will protect the soles of your feet far better than any other option.
Just my PPO2's worth.
Cheers!
Rob
